Frequently Asked Questions

Ultraviolet is an advanced web proxy that uses service worker technology to intercept and rewrite HTTP requests directly in your browser. It allows you to bypass internet restrictions, access blocked content, and browse privately — all without installing any software.

Yes. Ultraviolet features built-in leak prevention, URL encoding, and runs entirely client-side in your browser. We maintain a strict no-log policy and never store any user data, browsing history, or IP addresses.

Unlike a VPN which encrypts all device traffic and requires software installation, Ultraviolet operates within your browser tab using service workers. It's faster to set up, requires no downloads, and is specifically optimized for bypassing web content filters.

Absolutely! The Ultraviolet Proxy app works directly in any modern browser — Chrome, Firefox, Safari, Edge — on both desktop and mobile. No separate app download is needed since it functions as a full browser-based proxy app right from our website.

Ultraviolet uses advanced URL encoding and obfuscation techniques to minimize detection. While no proxy can guarantee 100% undetectability, Ultraviolet is designed to be extremely difficult for standard network monitoring tools to identify.

Yes! Our basic proxy service is completely free with 5GB monthly bandwidth. For unlimited bandwidth, premium speeds, and advanced features, check out our Pro and Enterprise plans.

If Ultraviolet Proxy is not working, try these fixes: clear your browser cache and cookies, disable browser extensions that may interfere (especially other proxy or VPN extensions), or switch to a different browser. Service workers occasionally need to be re-registered — a hard refresh (Ctrl+Shift+R) usually resolves this. If issues persist, your network may have updated its blocklist; try accessing from a different connection or join our Discord community for live support.

The Ultraviolet Proxy Reddit community is a great place to find working proxy sites, share tips, and stay updated on new versions. The Ultraviolet Proxy Discord server offers real-time help, announcements, and a direct line to the development team. Search "Ultraviolet Proxy" on both platforms to find the active communities and get social proof from thousands of verified users.

Common Ultraviolet Proxy alternatives include Corrosion, Rammerhead, and Womginx — all service-worker-based web proxies. There are also many ultraviolet proxy sites and mirror websites that run the same technology. However, Ultraviolet remains the most actively maintained and sophisticated web proxy, with superior CAPTCHA support, blazing speed, and broad compatibility with modern websites.

The name "Ultraviolet" refers to the invisible, beyond-normal-spectrum nature of the proxy — it operates unseen inside your browser. Ultraviolet is used as an advanced web proxy to bypass internet censorship, unblock restricted websites, and browse privately without installing any software. It is widely used as a free ultraviolet proxy app for school networks, workplace content filters, geo-restricted streaming, and general private browsing.
